Board-to-board connector

Board-to-board connector description/claims

1. Field of the Invention

The present invention relates to a board-to-board connector, and particularly, to a board-to-board connector with an improved locking mechanism for firming up a plug.

2. The Related Art

A variety of electronic connectors have been used to make electrical connections between the circuits on different printed circuit boards. These printed circuit boards must be joined together with connectors in a manner to effectively and reliably interconnect the circuits on one printed circuit board to the circuits of another printed circuit board, in order to establish signal communication or power connection.

U.S. Pat. No. 5,876,217, issued Mar. 2, 1999, the disclosure which is hereby incorporated by reference in its entirety, discloses a connector system and method for connecting cooperating printed circuit boards and transferring high frequency radio frequency signals between the printed circuit boards. The connector assembly includes opposing plug and receptacle connector housings, each containing conductive terminals. The terminals of one of the connector housings, preferably the plug connector housing include body portion with separate contact and locking portions extending upwardly therefore and spaced apart from each other define a nest there between. The nest receives a portion of the other connector engage opposing sides of the other connector-housing portion. The contact portions fictionally engage the other connector-housing terminal while the locking portions positively engage recesses formed in the other connector housing.

When the connector mated, as designed above, the receptacle lacks for corresponding fixing portion to firm up the plug, thus the plug will not be firmed effectively when the plug inserted into the receptacle, and then the conductive terminals of the plug will not achieve reliable electronic contact with corresponding receptacle.

The present invention has been achieved in view of the above insufficiencies to provide a board-to-board connector with stable structure to firm up a plug.

An objective of the present invention is to provide a board-to-board connector which comprises a insulating housing and a plurality of terminals accommodated in the insulating housing. The terminals are mounted in corresponding terminal-receiving passages arranged in the insulating housing. The insulating housing has a base plate. A pair of first sidewalls protrudes upwards from the opposite longwise sides of the base plate. Further more, a pair of second sidewalls protrudes upwards from another opposite sides of the base plate. A central island portion protrudes upwards from the center of the base plate. The central island portion keeps a certain distance to the first sidewalls and the second sidewalls, thus a periphery-receiving place is formed between the central island portion and sidewalls. Fixing parts are formed on the inside wall of the first sidewall exposed in the periphery-receiving place.

When the connector mated with plug, the fixing part presses on the sidewalls of the plug. As a result, the periphery-receiving place snugly fits the plug and establishes a firm connection therebetween.

The present invention will be apparent to those skilled in the art by reading the following description of a preferred embodiment thereof, with reference to the attached drawings, in which:
